Patent CA-2270693-C (CA)
Title: Automatic stop jig
Inventor: KOECHER WOLFGANG
IPC: B27B27/04
Filed: 1999-05-07
Granted: 2011-02-01
Abstract: A miter saw or radial arm saw accessory comprising of a moveable stop- structure. Designed to function as a workpiece restraining stop by default. It is propelled by means of an apparatus composed of electrical or mechanical elements that move the stop- structure away from or towards the sawblade. As this apparatus is activated by the saw switch or other means, it moves the stop-structure away from the sawblade and into a non-restraining position. As a result this frees the restrained workpiece, that otherwise would be forcibly jammed during the sawing process.

Abstract: A security tag having a strap for securing the tag to an object to be protected and an electronic module connected to the strap for detecting an attempt to defeat the tag by short circuiting and severing the strap. The strap is formed of plural discrete conductors connected to the electronic module, which conductors are insulated from each other at least along a substantial length of the strap. Short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuit in between separate conductors can be detected by the electronic module as an alarm condition. Severance or misconnection of only one or a small number of the insulated conductors can be detected by the electronic module as not being an alarm condition.

Patent CA-2281003-C (CA)
Inventor: KIGUCHI JYUNPEI
IPC: C22B1/243

Granted: 2004-06-22
Abstract: A process for producing fired pellets by granulating finely-ground iron ore and subjecting the resulting granules sequentially to drying, dehydration, preheating, and firing, wherein said process comprises adding an additive to said finely-ground iron ore at the time of granulation, said additive reacting with iron ore to form a compound which has a melting point lower than the preheating temperature. Owing to the additive (or sintering auxiliary) added in a small amount to iron ore powder, it is possible to produce preheated pellets by using the existing grate kiln without increasing the amount of preheating energy. The resulting preheated pellets have improved strength and produce no adverse effect on finished pellets.

Title: Drinks can lid with closure cap
Inventor: KLOSE FRANK
IPC: B65D43/10
Filed: 1998-02-13
Granted: 2008-04-22
Abstract: The drinks can has an off-centre opening (4) in its lid (1), which is firmly connected to the body surface, and is fastened to the body surface by means of a flanged rim (3). A closure cap (8) is arranged in a rotatable but non-removable fashion, on this flanged rim (3). The closure cap (8) has two annular beads (13, 22) that are directed towards the lid (1), and of which the second annular bead (22) surrounds an opening (12) which has the same eccentricity as the opening (4) in the li d (1). The first annular bead (13) surrounds a closed region that comprises a sealing ring (16) and a deformable bulge (19). In the closed sta te of the drinks can, the sealing ring (16) rests on the apex of an annular bead (5) that surrounds the opening (4). The annular bead (13) is therefore also arranged to be off-centre, so that it surrounds the annular bead (5) when the closure cap (8) is in the appropriate rotation al position. After the convex bulge (19) has been pressed into a permanent concave position, the closure cap (8) can be rotated, so that the opening (12) in the closure cap (8) aligns with the opening (4) in the lid (1).

Abstract: A spout is used for confining the grain flow from an auger. The auger may be a combine or grain cart unloading auger. The spout includes a chute that mounts on the auger tube. A pressure relief opening in the chute is normally closed by a gate which opens if the pressure in the chute builds up beyond a set level to prevent plugging of the auger and consequent auger damage. The chute is rotatably mounted on the auger tube so that it will swing out of the way on contact with another object, for example a truck box being loaded.

Title: System for inspecting in-service gas distribution mains
Inventor: RAVE PHILIPPE
IPC: G01B7/13
Filed: 1998-06-26
Granted: 2005-04-12
Abstract: A system for inspecting in-service gas distribution mains is disclosed. Coiled tubing technology and magnetic flux leakage (MFL) technology are integrated to produce a new inspection system for low pressure, in-service distribution pipelines. The coiled tubing provides the means by which an inspection module employing MFL technology is inserted into, moved through, and removed from an in-service pipeline. A portable inspection system can thereby be moved to a desired location on a trailer. The sensor module comprises a plurality of magnet assemblies each having a Magnet N out, a Magnet S out and a magnet core, the magnet assemblies being conical in shape and being arranged into a circular array. The magnet array diameter is smaller than that of a pipe to be inspected, thus defining a radial air gap. The magnet array being constructed and arranged to provide a magnetic circuit having sufficient strength so as to be operable through the radial air gap. A centering mechanism is constructed and arranged to maintain the sensor module in concentric relation with the pipe to be inspected. This array provides an efficient method of packing the magnets to generate the very powerful magnetic field desired. The conical shape of the magnets in this assembly permits the unit to negotiate tighter bends than would be possible with a cylindrical assembly. The centering mechanism permits product bypass and minimizes removal of surface debris.

Title: Intelligent network interface device and system for accelerating communication
Inventor: STARR DARYL
IPC: G06F13/00
Filed: 1998-11-20
Granted: 2009-12-01
Abstract: An intelligent network interface card or communication processing device (30) works with a host computer (20) for data communication. The device provides a fast-path (159) that avoids protocol processing for most messages, greatly accelerating data transfer and offloading time-intensive processing tasks from the host CPU (28). The host retains a fallback processing capability for messages that do not fit fast-path criteria, with the device providing assistance such as validation even for slow-path messages, and messages being selected for either fast-path or slow-path (158) processing. A context (50) for a connection is defined that allows the device to move data, free of headers, directly to or from a destination or source in the host. The context can be passed back to the host for message processing by the host. The device contains specialized hardware circuits that are much faster at their specific tasks than a general purpose CPU. A  preferred embodiment includes a trio of pipelined processors (482, 484, 486) devoted to receive, transmit and utility processing, providing full duplex communication for four Fast Ethernet nodes.
